When the terminal is completely inserted into the connector and the flexible locking lance locks the terminal, one end of the insertion inspection pin enters the bending space and the movable member comes into contact with the circuit conductor. Has become. Therefore, the continuity inspection pin is connected to the terminal of the connector and the movable member via the elastic member and the circuit conductor. The external circuit following the movable member and the wire following the terminal are connected in advance to the continuity inspection device, and the terminal, the continuity inspection pin, the elastic member, the circuit conductor, and the movable member are electrically connected to form a closed circuit, and the continuity is established. The inspection device displays the inspection result OK. When the insertion of the terminal in the connector is incomplete and the flexible locking lance remains bent, or when the terminal is completely inserted, the flexible locking lance is bent or deformed due to hooking or deformation. If not restored, one end of the insertion inspection pin abuts against the tip of the flexible locking lance, and the other end of the insertion inspection pin retracts the movable member against the elastic bias. Thereby, the contact between the circuit conductor and the movable member is released, and the continuity inspection device displays an inspection result NG (defective). In addition,
If one end of the continuity test pin is in contact with the terminal even though the terminal is slightly incompletely inserted, the continuity test pin, the elastic member, and the circuit conductor are in contact with each other. Since the inspection pin presses the movable member in the contact release direction, conduction cannot be established, and the inspection result is NG.
